Detailed Description
As shown in fig. 2 and 3, the sectorial ladle with the sectorial slag trap of the present invention comprises: sector and slag notch district 9, slag notch district 9 is in the upper end of sector, its characterized in that: the slag-stopping plate is characterized in that a sector area is composed of a pouring gate arc 3, a triangular straight baffle 8, a triangular bottom baffle 7, a ladle bottom baffle 6 and a sector baffle 5 which are sequentially connected, a slag-stopping plate 1 is further arranged in the sector area, the pouring gate arc 3 is an arc which takes a sector ladle rotating center 4 as a circle center and protrudes towards the slag-discharging area 9, both the slag-stopping plate 1 and the sector baffle 5 are arcs which take the sector ladle rotating center 4 as the circle center, the arc of the sector baffle 5 occupies 40-70 degrees of the radius of the upper circle where the arc is located, the radius of the slag-stopping plate 1-the sector ladle rotating center 4 is 1/5-1/3 degrees of the radius of the sector baffle 5-the sector ladle rotating center 4, and the included angle between the arc of the slag-stopping plate 1 and the sector ladle rotating center 4 is larger than the included angle between the arc of the sector baffle 5 and the sector ladle rotating center 4. The slag trap 1 is arranged in a sector area above the triangular bottom baffle 7, and the distance between the bottom end of the slag trap 1 and the triangular bottom baffle 7 is the same. The slag trap 1 is made of a refractory material.
The rotation center 4 of the fan-shaped ladle is positioned below the slag discharging area 9, and the radius of the gate arc 3 is smaller than the height of the slag discharging area 9. The bottom-covering baffle 6 is a straight line which connects the fan-shaped baffle 5 and the gate arc 3 in a tangent mode. The triangular straight baffle 8 is a vertical straight line tangent to the arc of the gate arc 3. The triangular bottom baffle 7 is a straight line connecting the triangular straight baffle 8 and the ladle bottom baffle 6, and the included angle between the straight line and the horizontal line is-6 degrees to-15 degrees. And a refractory layer 2 is arranged in a sprue circular arc 3, a triangular straight baffle 8, a triangular bottom baffle 7, a ladle bottom baffle 6 and a fan-shaped baffle 5 of the fan-shaped area.
Compared with the existing fan-shaped ladle, the fan-shaped ladle with the fan-shaped slag trap has the advantages that the slag trap 1, the fan-shaped baffle 5 and the pouring gate arc 3 are concentric circles, and the rotating center 4 of the fan-shaped ladle is the actual rotating center of the fan-shaped ladle in the pouring process. The bottom baffle 6 of the fan-shaped bag is shaped as shown in figure 2. A fan-shaped slag trap 1 is added inside the fan-shaped area. The molten iron flows out from the space between the slag trap 1 and the triangular bottom baffle 7. The sectional area formed by the distance between the slag trap 1 and the triangular bottom baffle 7 is larger than that of the fan-shaped ladle gate.

2. The outflow mode of molten iron is changed from the original mode that the molten iron flows from top to bottom layer by layer to flow out from the middle of the fan-shaped ladle, the light impurities in the molten iron can float upwards within sufficient time in the outflow mode, and the impurities which float upwards cannot flow out along with the molten iron, so that the molten iron flowing out of the fan-shaped ladle is purified, and the casting defect probability caused by slag blocks is reduced.
3. The slag trap 1 extends into the plane of the ladle bottom baffle 6, so that the residual molten iron in the fan-shaped ladle after the pouring is finished is as little as possible.
4. The slag baffle plate 1 extends into the plane of the ladle bottom baffle plate 6 to prevent scum from flowing out of the fan-shaped ladle along with molten iron at the last stage of pouring.
5. The triangular bottom baffle 7 is designed into an inclined plane instead of a horizontal plane, so that a small amount of residual molten iron and blocked scum can smoothly return to the bottom of the ladle along the inclined plane of the triangular bottom baffle 7 after the pouring of the fan-shaped ladle is finished, and the blockage cannot be caused.
6. The sectional area of the gap between the slag trap 1 and the triangular bottom baffle 7 is larger than that of the pouring gate of the fan-shaped ladle, so that the consistency of the molten iron liquid levels on two sides of the slag trap 1 in the casting process of the fan-shaped ladle is ensured.
The foregoing description is illustrative of the present invention and is not to be construed as limiting thereof, the scope of the invention being defined by the appended claims, which may be modified in any manner without departing from the spirit of the invention.
